            Bug ID: 108591
           Summary: void{} does not error out in 12.1
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: Mark_B53 at yahoo dot com
  Target Milestone: ---

void fn1() {
    return void{};  // fails in gcc 11.3, passes in gcc 12.1
}
void fn2() {
    return void();  // passes in both gcc 11.3 and gcc 12.1
}

I would not have expected fn1 to be legal C++.
